Restless REM Sleep May Contribute to Mood, Anxiety Disorders

Posted by in category: neuroscience

Restless rapid eye movement (REM) sleep impedes emotional processing, which may contribute to mood and anxiety disorders, new research suggests.

A team of Dutch investigators used fMRI to scan the brains of participants who underwent a stressful experience — in this case, hearing themselves sing out of tune. Brain activity was measured using electroencephalography (EEG).

The next morning, after spending the night in a sleep laboratory, participants were subjected to the same unpleasant experience. Those who had experienced REM sleep were less distressed, whereas those with restless REM sleep were once again upset.

‘Game changing’ cancer treatment can extend patients’ lives

Posted by in category: biotech/medical

CANCER patients with previously incurable tumours have been given hope by a life-extending treatment which can double the length of time a person can live cancer-free.

The new worldwide medical trial involving the Beatson Cancer Centre in Glasgow has discovered a high-precision radiation treatment which can extend a patient’s lifespan by more than a year. Patients diagnosed with metastatic tumours – cancer which had spread to other parts of the body – were thought to be incurable, but researchers on the clinical trial have found that aggressive radiation therapy can increase life expectancy.

Hailing the research as a “game-changer”, scientists gave almost 100 cancer patients from Scotland, Canada, the Netherlands and Australia “substantially higher doses of radiation” to areas where their cancerous tumours had spread. Patients receiving the treatment, known as stereotactic ablative radiotherapy, lived 13 months longer on average.

Audi A9 Concept Car Repairs Itself And Changes Color

Posted by in categories: nanotechnology, transportation

Imagine an amazing sports car that could repair itself from damage and automatically change color! Well that’s exactly what Spanish designer Daniel Garcia was thinking of when he created this awesome concept design for the Audi A9. He got some inspiration for this particular design from Santiago Calatrava’s buildings in his hometown of Valencia. Calatrava’s architectural style looks very modern and futuristic, which is exactly what we would describe this car to look like. The windscreen and roof are to be made from a nanotechnology material that can auto-repair and adjust colors. This material isn’t even something that exists right now, so will it be a long time before we actually get to see something like this in action? The idea of it sounds awesome though, right?!

Seabed mining is coming — bringing mineral riches and fears of epic extinctions

Posted by in categories: business, existential risks, sustainability, transportation

Now, it seems this nascent industry’s time has come. A growing demand for batteries to power electric cars and to store wind and solar energy has driven up the cost of many rare-earth metals and bolstered the business case for sea-bed mining. What’s more, the industry’s long-awaited regulations — in the form of a mining code — are due to be finalized by 2020, putting in place a process whereby contractors can apply for 30-year licences to mine assigned ‘claim areas’ in parts of the international sea bed such as the CCZ. Already, miners are exploring the potential wealth of these claim areas, but no commercial extraction will begin until the regulations are in place. Investments in this industry are now growing.

Plans are advancing to harvest precious ores from the ocean floor, but scientists say that companies have not tested them enough to avoid devastating damage.

Happy Birthday To Vera Rubin: The Mother Of Our Dark Matter Universe

Posted by in category: cosmology

Vera Rubin is shown here in 1974, analyzing data from different portions of a galaxy to ascertain its rotational properties. The discovery that the effects of gravity did not trace out the same path that the starlight does was one of the most important discoveries of the 20th century, and brought dark matter into the mainstream of science from the fringes, where it had languished for most of the 20th century. Her work changed our conception of the Universe forever.

Unconventional phenomena triggered by acoustic waves in 2-D materials

Posted by in categories: energy, quantum physics

Researchers at the Center for Theoretical Physics of Complex Systems (PCS), within the Institute for Basic Science (IBS, South Korea), and colleagues have reported a novel phenomenon, called Valley Acoustoelectric Effect, which takes place in 2-D materials, similar to graphene. This research is published in Physical Review Letters and brings new insights to the study of valleytronics.

In acoustoelectronics, surface (SAWs) are employed to generate . In this study, the team of theoretical physicists modelled the propagation of SAWs in emerging 2-D , such as single-layer molybdenum disulfide (MoS2). SAWs drag MoS2 electrons (and holes), creating an electric current with conventional and unconventional components. The latter consists of two contributions: a warping-based current and a Hall current. The first is direction-dependent, is related to the so-called valleys—electrons’ local energy minima—and resembles one of the mechanisms that explains photovoltaic effects of 2-D materials exposed to light. The second is due to a specific effect (Berry phase) that affects the velocity of these electrons travelling as a group and resulting in intriguing phenomena, such as anomalous and quantum Hall effects.

The team analyzed the properties of the acoustoelectric current, suggesting a way to run and measure the conventional, warping, and Hall currents independently. This allows the simultaneous use of both optical and acoustic techniques to control the propagation of charge carriers in novel 2-D materials, creating new logical devices.
